Summary of jquery cookie usage_jquery

jQuery cookie is a good cookie plug-in. The general usage method is as follows
example $.cookie('name', 'value');
Set the value of the cookie and set the value of the name variable to value
example $.cookie('name', 'value', {expires: 7, path: '/', domain: 'jquery.com', secure: true});
Create a new cookie including the expiration path Domain name, etc.
example $.cookie('name', 'value');
Create a new cookie
example $.cookie('name', null);
Delete a cookie

var account= $.cookie('name');
Take a cookie(name) value and give it to myvar

The code is as follows

Copy codeThe code is as follows:

jQuery.cookie = function(name , value, options) {
if (typeof value != 'undefined') { // name and value given, set cookie
options = options || {};
if (value === null ; number' || options.expires.toUTCString)) {
var date;
if (typeof options.expires == 'number') {
date = new Date();
date. setTime (date.getTime() (options.expires * 24 * 60 * 60 * 1000));
                                                                                           = '; expires=' date.toUTCString(); // use expires attribute, max-age is not supported by IE
}
var path = options.path ? '; path=' options.path : '';
var domain = options.domain ? '; domain=' options.domain : '';
var secure = options.secure ? '; secure' : '';
document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');
} else { // only name given, get cookie
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i ) {
var cookie = jQuery.trim (cookies[i]); =')) {
                               cookieValue =                                                                                                                                                         cookieValue =            🎜>       }
                      return cookieValue;                                                  
};


Then I looked at the cookie operation method in Discuz!
as follows, and found that there is missing a traversal; the processing of divided arrays




Copy code


The code is as follows:

function getcookie(name) {
var cookie_start = document.cookie.indexOf(name);
var cookie_end = document.cookie.indexOf(";", cookie_start);
return cookie_start == -1 ? '' : unescape(document.cookie.substring(cookie_start name.length 1, (cookie_end > cookie_start ? cookie_end : document.cookie.length)));
}
function setcookie(cookieName, cookieValue, seconds, path, domain, secure) {
var expires = new Date();
expires.setTime(expires.getTime() seconds);
document.cookie = escape(cookieName) '=' escape(cookieValue)
(expires ? '; expires=' expires.toGMTString() : '')
(path ? '; path=' path : '/')
(domain ? '; domain=' domain : '')
(secure ? '; secure' : '');
}
